Oh Mary my heart goes out to you, so fustrating and upsetting trying to figure out your wee girl, i still think maybe some of the medication could be affecting her, you know yourself when you take medication it can do funny things to you,everyone is different and has different reactions, i know Ash certainly has been behaving a bit odd since we started his medication, he used to stay indoors all the time by the heater, not anymore,things like that, however i suspect he is scared we are going to pill him again,who really knows, i hope Dr Lee can shed some light on her behaviours, and you could well be right, she maybe becoming senile,let us know how you get on when you can,until then HUGS all around and the best of luck with Puddy.
